NAME

       backup_addvolentry - Defines a volume entry in a volume set

SYNOPSIS

       backup addvolentry -name <volume set name>
           -server <machine name>
           -partition <partition name>
           -volumes <volume name (regular expression)>
           [-localauth] [-cell <cell name>] [-help]

       backup addvole -n <volume set name>
           -s <machine name>
           -p <partition name>
           -v <volume name (regular expression)>
           [-l] [-c <cell name>] [-h]

DESCRIPTION

       The backup addvolentry command adds a volume entry definition to the existing volume set
       named by the -name argument. A volume entry definition can match one or more volumes,
       depending on the combination of the -server, -partition, and -volumes arguments.

       For the -server and -partition arguments, provide either

       ·   The name of one machine or partition.

       ·   The metacharacter expression .* (period and asterisk), which matches every machine
           name or partition name in the Volume Location Database (VLDB).

       For the -volumes argument, specify a combination of alphanumeric characters and one or
       more metacharacters to wildcard part or all of the volume name. OPTIONS lists the
       acceptable metacharacters.

CAUTIONS

       It is best to issue this command in interactive mode. If issuing it at the shell prompt,
       enclose any strings containing metacharacters in double quotes, or escape the
       metacharacters with other delimiters, to prevent the shell from interpreting them. Adding
       volume entries to a temporary volume set is possible only within the interactive session
       in which the volume set was created.

OPTIONS

       -name <volume set name>
           Names the volume set to which to add this volume entry definition.  The volume set
           must already exist (use the backup addvolset command to create it).

       -server <machine name>
           Defines the set of one or more file server machines that house the volumes in the
           volume entry. Provide either one fully-qualified hostname (such as "fs1.abc.com") or
           the metacharacter expression ".*" (period and asterisk), which matches all machine
           names in the VLDB.

       -partition <partition name>
           Defines the set of one or more partitions that house the volumes in the volume entry.
           Provide either one complete partition name (such as "/vicepa") or the metacharacter
           expression ".*" (period and asterisk), which matches all partition names.

       -volumes <volume name>
           Defines the set of one or more volumes included in the volume entry. Specify the
           volumes by name, by using any combination of regular alphanumeric characters and one
           or more of the following metacharacter expressions:

           "." The period matches any single character.

           "*" The asterisk matches zero or more instances of the preceding character.  Combine
               it with any other alphanumeric character or metacharacter.

           "[ ]"
               Square brackets around a list of characters match a single instance of any of the
               characters, but no other characters; for example, "[abc]" matches a single "a" or
               "b" or "c", but not "d" or "A". This expression can be combined with the asterisk.

           "^" The caret, when used as the first character in a square-bracketed set, designates
               a match with any single character except the characters that follow it; for
               example, "[^a]" matches any single character except lowercase "a". This expression
               can be combined with the asterisk.

           "\" A backslash preceding any of the metacharacters in this list makes it match its
               literal value only. For example, the expression "\." (backslash and period)
               matches a single period, "\*" a single asterisk, and "\\" a single backslash.
               Such expressions can be combined with the asterisk (for example, "\.*" matches any
               number of periods).

           Perhaps the most common metacharacter expression is the period followed by an asterisk
           (".*"). This expression matches any string of any length, because the period matches
           any character and the asterisk means any number of that character. As mentioned, it is
           the only acceptable metacharacter expression for the -server and -partition arguments.
           In a volume definition it can stand alone (in which case it matches every volume
           listed in the VLDB), or can combine with regular characters. The following example
           matches any volume name that begins with the string "user" and ends with "backup":

              user.*backup

       -localauth
           Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile
           file. The backup command interpreter presents it to the Backup Server, Volume Server
           and VL Server during mutual authentication. Do not combine this flag with the -cell
           argument. For more details, see backup(8).

       -cell <cell name>
           Names the cell in which to run the command. Do not combine this argument with the
           -localauth flag. For more details, see backup(8).

       -help
           Prints the online help for this command. All other valid options are ignored.

EXAMPLES

       The following command adds a volume entry to the volume set called "sys". The entry
       matches all volumes on any machine or partition whose names begin with the string
       "sun4x_56" followed by a period:

          backup> addvolentry sys .* .* sun4x_56\..*

       The following command adds a volume entry to the volume set called "fs2", to match all
       volumes on the /vicepb partition of file server machine "fs2.abc.com". Because it is
       issued at the shell prompt, double quotes surround the metacharacters in the -volumes
       argument. (The command is shown here on two lines only for legibility reasons.)

          % backup addvolentry -name fs2 -server fs2.abc.com \
                               -partition /vicepb -volumes ".*"

       The chapter in the OpenAFS Administration Guide about configuring the AFS Backup System
       presents additional examples as well as advice on grouping volumes.

PRIVILEGE REQUIRED

       The issuer must be listed in the /etc/openafs/server/UserList file on every machine where
       the Backup Server is running, or must be logged onto a server machine as the local
       superuser "root" if the -localauth flag is included.
